In Git, the term "origin" refers to the default remote repository for your project. Setting up the origin is a crucial step when starting to work with repositories in Git, as it defines the primary upstream repository that you will push to and pull from. This guide will walk you through the steps to set and modify the origin in your Git configuration and explain how to push changes with the correct upstream settings.
Setting the origin in Git
Step 1: Create or clone a repository
If you don’t already have a local repository, create one with:
git init
Alternatively, you can clone an existing repository, which will automatically set the origin:
git clone <repository-url>
This command clones the repository and sets the remote named 'origin' to the URL provided.
Step 2: Setting a new origin
If your repository does not have an origin set, or you need to change the existing origin, use the following commands:
Add a new origin
If no remote named 'origin' exists, add it with:
git remote add origin <repository-url>
Replace <repository-url> with the URL of your remote repository.
Change an existing origin
If you need to change an existing origin, use:
git remote set-url origin <new-repository-url>
This command updates the URL associated with the remote named 'origin'.
Step 3: Verify the origin setting
After setting or changing the origin, verify it with:
git remote -v
This command lists all remotes configured for your repository, showing the URLs associated with fetch and push operations for each remote.
Pushing changes and setting the upstream
Basic push
To push changes to the origin, use:
git push origin <branch-name>
Replace <branch-name> with the name of your local branch.
Set upstream with push
When pushing a new branch or if you want to set the tracking relationship between your local branch and a remote branch, use:
git push --set-upstream origin <branch-name>
This command pushes your branch to the remote named 'origin' and sets it to track the remote branch of the same name. Subsequent pushes can be done with just git push.
Setting the default push behavior
You can configure the default behavior of git push by setting the push.default configuration. For instance, setting it to simple ensures that Git only pushes the current branch to the corresponding remote branch that 'git pull' would pull from:
git config --global push.default simple
By correctly configuring and setting the remote origin in Git, you streamline the workflow of pushing to and pulling from the central repository, making your Git experience more efficient. Remember to regularly check and update your remote settings to align with any changes in the repository URLs or project structure.

Frequently asked questions
Can I have multiple remotes besides origin?
Yes, you can add multiple remotes to your repository. Use git remote add <name> <url> to add additional remotes (e.g., git remote add upstream <url>). You can then push to specific remotes using git push <remote-name> <branch-name>.
What's the difference between HTTPS and SSH URLs for origin?
HTTPS URLs (like https://github.com/user/repo.git) work with username/password or token authentication, while SSH URLs (like git@github.com:user/repo.git) use SSH key authentication. SSH is generally more secure and convenient for frequent operations, while HTTPS is easier to set up initially.
How do I remove the origin remote?
You can remove the origin remote using git remote remove origin. This is useful if you want to completely change the remote repository or if you're working with a local-only repository.
What happens if I push without setting upstream?
If you push without setting upstream using git push origin <branch-name>, Git will push your changes but won't establish a tracking relationship. This means future git push commands without arguments will fail, and you'll need to specify the remote and branch each time.
